Final answer:
The Iceman's intestines revealed that his diet included meat and grain, offering a glimpse into the dietary practices of Paleolithic humans, consisting the plant and animal-based foods and evidencing their adaption to the environment.
Step-by-step explanation:
DNA analysis of the contents of the Iceman's intestines has provided insight into the foods he had consumed. This research indicates that the Iceman's diet included items like meat and grain. The analysis of his intestines shows he had eaten high-quality foods, which provides important clues regarding the dietary practices and lifestyle of people during that time.
This discovery not only sheds light on the Iceman's last meals but also demonstrates the broader eating habits and nutritional strategies employed by his society. What does this prove? The evidence gathered from the Iceman helps to understand how early humans adapted to their environment, their health, and the availability of different foods.
It also serves as a direct connection to the paleo diet of that era, revealing that Paleolithic humans had a balanced diet consisting roughly of 65 percent plant-based foods and 35 percent animal-based foods. This ratio is consistent across different geographical areas, regardless of specific food types available, thus providing a framework for modern discussions about healthy diets.
